Funny you should bring this up. I am currently making a list of what to keep in my kit as the weather improves. Aside from parts, I will likely keep the following with me:
allen wrenches
hammer
zip ties
electrical tape, duct tape
screwdrivers
loctite
extra bobbins
multi-tool
I do have a canister of fix-a-flat and a small compressor
